PlayStation Network is scheduled to undergo routine maintenance tomorrow, August 11th, from about 8am until approximately 7pm Pacific Time. During this time, registration and Account Management will be inaccessible, including the password reset process. While some users may experience difficulty signing into PSN and the PlayStation Store, the majority of users will be able to play online as well as sign in to external sites that require PSN authentication (like this one).
Stay tuned to the PlayStation Twitter feed for updates and a notice when maintenance has concluded.
We apologize for any inconvenience this may cause.
